Code: Select all
Non-static nested classes, unlike normal package classes, can have any type of accessibility.
But in Jeanne Boyarsky, Scott Selikoff' book says this regarding Local inner class:
They do not have an access specifier.
They cannot be declared static and cannot declare static fields or methods.
I am not quite sure which one is correct. The non-static inner class can have constant members but no static methods are allowed, right? What about access modifier? thank you!

Observe the statements carefully. First one says non static nested classes and second one says local inner classes. Both are correct.

Are these two conflict each other regarding the access modifier? Thanks

Non static nested class:
class Outer{
public|private|protected class Inner{ <<---- Any access modifier
}
}
Local Inner Class :
someMethod(){
class LocalInnerClass { <<--- can't have any access modifer
}
}

Thanks, that's what I thought in the first place. I am confused since the solution says non-static classes can have any access modifier but it should exclude local inner class.

Sure, enhanced the statement to avoid the confusion.
thank you for your feedback!
